VIBRATING ENGINE.

SPECIFICATION forming part of Letters Patent No. 399,327, dated March 12, 1889. Application filed May 3, 1888. Serial No. 272,636. (No model.)

To all v7/.0712. it 71mg/ concern.:

Be it known that I, DEXTER D. HARDY, n eitizen of the United States, residingl at (fihicago, in the county of Cook and State ot Illinois, have invented certain new and useful Improvements in Vibrating` En gines, oi wh ich the following is a specification.

My present invention relates to vibrating engines; and itconsists of improvements upon certain devices in such engines h itherto patented to nie--to wi t., bv Letters Patent ot the United States Nos. 375,287 and $73,239, l

both dated November 15, 1887.

The object ot my present invention is io make such an engine reversible, and at `the same time io maintain its simplicity of eonstruction. chinery illustrated in drawings, in which- Figure l .represents a top plan view of a vibrating engine, with a part of the steameh'est and upper part of the easing broken away to show the slide-valve and stemn-ports. Fig. L is a vertical longitudinal section taten on the line l l of llig. l, with the cranks and pistons in their extreme vertiiwal imsitions,

the accom panyi ng Fig. 2i is a vertieal cross-semmaiaken on the` line L 2 of Fig. i, looking in ihe direction of the arrow, with the cranks turned a quarterrevolution and the cylinders in their extreme horizontal positions. Fig, A-l is a plan section taken on the line 1i Si oi' Fig. Si, looking in the direction oi." the arrow. Fig. 5 is a bottom plan view ot' the top of The easing. *alten on the line l yl ot' Fig. Si, lo ,ing in the direction of the arrow.

Like letters reler to like parts in all the drawings.

In the drawings, A is the casing designerfl to contain the cylinders, pistons, and slides. .B and I3 are cylinders. The former about twice as large as the lati er. (y and (l are pistons working in these, respectively.

l) is a steam-hest, and D a pipe leznling to it from the boiler.

d and (Z are stean'l-lwris leading l'rom the steam-chest to the end of the c vlim'ler l opposite to the main shal't.

q is an exhaust-port passing through the valve-seat D2 into the exibau The inner sides ol' the lowei l attain lsneh object bythe nulisi spare somewhat grenier than the caliber ol' per ends are separat ed ii'rom each other by a distance a littlegreal'erthan ihelength of the cavity in the slide-valve (i,

E is a pipe leading from ihestenmehest or boiler to the end of the cylinder li opposite to the main shat't F.

F F are cranks forming parl ol", the main shaft. The pistons are journaled io the crank-pins in any suitable manner.

A A are the heads olf the casing A. Bearings are formed in these for the main shaft. The pistons talco hold ot' the crank-pins directly without the use of any connecting-rods.

(i is a slide-valve of the ordinary type.

l l are slides in which the erossdieads .,l` .l werk.

lhe maeh inery above described is operated as follows: Adjust the slide-valve ('r so that its cavity will open into the steam-port d. Admit steam inio the c vlil'nlm.' i. 1t is 0bvions that the engine will now begin io act, the piston (l movingl toward the main shaft and the piston in theoppositedirection. At the same time the cylinder B vibrates, its opening is brought beneath the steam-port d, steam rushes through this, and on account oi' the grenier area ot pressure on the piston t? it moves toward the main. shaft and the piston C in the opposiie direction. The cylinder li vibrai ing baek on the completion of a semi-revolution pf its crank, steam is out ott' by an end flange et the cylinder pmsing beneath the end ot' the steam-port d, Ln; opening oi the eylinder is brought beneath the end el' the stehn-port d', and the steam escapes through this, whereupon the above operation is repeated. To reverse the action ot' the engine, move the slide-valve G so that its cavity will open inl'o the steanrport d.

lla-ving now lnlly described my invention, what l claim as new, and desire lo secure by Letters latent, is-

l. ln avibraiing engine, the eombimiiion ol' iwo evlinders having dill'ereni oalibers, one of said cylinders having steam therein con sianily, the. other reeeiving and exhaust-ing steam by its own movement, whereby the sleam-poris are mened and closed, .substantially as stated.

ln a vibrating engine, iho combination i l, Vif of the Cylinder opening directly into the pipe E, lending .'roni the steam chest orlioiler, the cylinder '13, l'lm'ingl :t caliber greater than that of t-he eyliiider l', the exhaust-port g, the exhaust-passage ll, and the stemn-port-s (Z and d', whereby stezun is received and exhausted intermittently by the movement of said cylinder i), and the pistons C and (l, moving in said cylinders, respectively, and connect-ed with the mitin shnlft by eritnk's placed thereon dizimetrien-lly opposite to each other, sul'istmit-i2111)'T as und Afor the purposes stated.
